Candlestick formation · Bearish
What is it, in one line
Long green, a small gapped body, then a long red close.
Bearish · 3 candles · verdict: rule and thresholds below
Long green, a small gapped body, then a long red close. The engine checks the formation as an executable condition over open, high, low and close, with a trend filter applied before the count is kept.
Method
The mirror of the morning star: a long up candle, a small-bodied candle clear above it, then a down candle closing back through at least half the first body.
The traditional claim
Traditionally read as a bearish reversal formation, and usually paired with the morning star as its counterpart.
How this detection is wrong
Mirror of morning-star. Same gap and penetration semantics.
Published so the count can be reproduced. Every figure below is a parameter of the rule, not a preference: change one and the occurrence count changes with it.
| Parameter | Meaning | Default |
|---|---|---|
| trendPeriod | bars of prior trend inspected | 5 |
| minPriorSlope | prior slope must be above | 1 |
| minFirstBodyAtr | first body, at least, in ATR | 0.6 |
| maxStarBodyRatio | star body, at most, relative to the bar before | 0.4 |
| penetration | how far the close must push into the previous body | 0.5 |
| minGapAtr | gap between bars, at least, in ATR | 0 |
| atrPeriod | bars of ATR used to size everything below | 14 |
These share enough geometry that a detector can return more than one of them on the same bar. The engine reports every match rather than picking a winner.
Every pair on the site that can be mistaken for another, and what separates each: the look-alikes index.
The mirror of the morning star: a long up candle, a small-bodied candle clear above it, then a down candle closing back through at least half the first body. The detector also requires a prior uptrend, so the same shape in the wrong context is not counted.
It is read as bearish. Traditionally read as a bearish reversal formation, and usually paired with the morning star as its counterpart.
Mirror of morning-star. Same gap and penetration semantics.
As an executable rule over open, high, low and close, with 7 named parameters — including bars of prior trend inspected 5, prior slope must be above 1, first body, at least, in ATR 0.6 — all published on this page so the count can be reproduced. Strict and loose variants are defined as well, so the sensitivity of the count to those thresholds is visible rather than assumed.
Measurement pending re-run
No hit rate is published here yet. The run that would supply one was computed on engine ca6d9e36c81c; the engine is now cfb08765de7c. Its candlestick rows included the still-forming bar, and it predates the chart formations entirely, so those figures have been withdrawn rather than published with a caveat. The definition above is unaffected: it is what the detector tests, and no re-run changes it.
Same shape, opposite reading
The shapes are close, and the prior trend is what decides which one fired: this rule requires a preceding uptrend, its mirror a preceding downtrend.
Morning Star: A long down candle, a small candle below it, then an up candle closing back through the first.
